Why Choose the SBA5?

The SBA5 was developed for shooters looking for a middle ground between the lightweight profile of the SBA3® and the more reinforced feel of the SBA4®. It offers additional support and updated geometry while maintaining a streamlined footprint and familiar adjustment controls.

Whether you’re building a defensive firearm, a compact range setup, or a PDW-style configuration, the SBA5 provides a versatile option that balances support, durability, and compact dimensions.

SBA5 Compatibility

The SBA5 is designed for platforms that utilize a standard mil-spec carbine receiver extension, making it compatible with a wide variety of AR-pattern firearms and calibers.

The SBA5 is commonly used with:

• AR-15 platforms chambered in 5.56 NATO, .300 Blackout, and 7.62×39
• AR-9 and other pistol-caliber firearm variants
• Compact defensive firearm configurations
• Range-focused AR builds
• PDW-style firearm platforms utilizing mil-spec buffer systems

Because receiver extensions can vary slightly between manufacturers, overall fit may differ depending on the specific buffer tube being used.

What’s the Difference Between SBA3, SBA4, and SBA5?

The SBA3®, SBA4®, and SBA5® all utilize a 5-position adjustable design, but each offers a different balance of size, weight, and support.

The SBA5 features an updated, reinforced design that balances rigidity with a compact footprint. It offers increased structural support compared to the SBA3 while maintaining a modern adjustable configuration.

For shooters seeking a combination of streamlined dimensions and enhanced support, the SBA5 sits squarely between the SBA3 and SBA4 in both profile and handling characteristics.

• Width: Approximately 2.1″
• Length: Approximately 6.125″
• Weight: Approximately 9.5 oz

The SBA3 is the lightest and most minimalist option in the lineup. It is designed for shooters prioritizing compact dimensions and reduced weight.

• Width: Approximately 2″
• Length: Approximately 6.75″
• Weight: Approximately 6.75 oz

The SBA4 is built for shooters seeking maximum rigidity and durability. Its reinforced construction and robust design make it an excellent option for larger firearm builds or applications where structural strength is a priority.

• Length: Approximately 7.5″
• Weight: Approximately 10 oz
